  • Page 5: Application Information

    1. APPLICATION INFORMATION The tester is used for determining the Brinell hardness of un-quenched steel, cast-iron, nonferrous metals and soft bearing alloys. This tester can be used in metallurgical plants, machine manufacturing plants, metal working plants , industrial laboratories, and laboratory environments. The measuring range of hardness is 8-450 HBS when steel ball indenter is used, and 8-650 HBW when a tungsten carbide ball indenter is used.

  • Page 6: Mechanical Description

    3. MECHANICAL DESCRIPTION 3.1 Frame and anvil (See Parts Location Diagram on Page 8) The hardness tester has a cast iron frame (1). An elevating screw seat (18) is set on the stage at the front of the frame. The removable anvil (24) is set on the elevating screw (22), which is fitted precisely into the seat (18).

  • Page 7: Electronic Control System (See Parts Location Diagram

    3.5 Electronic Control System (See Parts Location Diagram on Page 8) The electronic control system consists of a solenoid (23) and printed wiring board (30), etc. Depress the start button (5A) to bring the solenoid into action. The pneumatic cylinder (8) starts to empty, and the indicator light for loading (1A) is lit. The piston rod (6) descends, dropping the fork rocker (5) slowly downward and the roller is separated from the large lever.

  • Page 8: Installation (See Parts Location Diagram On Page 8)

    4. INSTALLATION (See Parts Location Diagram on Page 8) The tester should be installed in a dry, clean room without corrosive gases or large amount of vibration. The base for the tester should be rigid and flat and able to sup- port weight of tester - 570 lbs.
  • Page 9 The weight hanger (3) should be hung on the knife edge of the load lever (4) and the weights added and rotated to different amounts so that the slots on the weights are offset to prevent them from accidentally being knocked off the hanger. (See photo at right) Place the hanger on the knife edge at the end of the large lever.

    5. TEST SETUP and OPERATION 5.1 Setting up Indenter and Anvil INDENTER Select the proper indenter according to the desired load in Ball accordance with ASTM E-10. Indenters consist of a ball holder, cap and ball. Clean any oil from the surface of the Holder ball and the ball holder before installing.

  • Page 11: Load A Test Specimen

    5.3 Load a Test Specimen Put a test specimen on the anvil and turn the handwheel (21) of the elevating screw until the piece contacts the indenter. Continue turning the handwheel until the indenter is lifted slightly and the handwheel slips. If the handwheel does not reach a point where it slips, the ball detent (19) may need adjustment.

  • Page 13: The Brinell Test Method

    7. THE BRINELL TEST METHOD 7.1 The ASTM Specification Brinell testing is covered by the ASTM standard E-10. The ASTM specification can be purchased from the ASTM (American Society for Testing and Materials) at 1916 Race Street, Philadelphia, PA 19103. The following test method is not a complete descrip- tion of the standard.
  • Page 14 7.3 Other Conditions for Testing - The angle of test force should be within 90L K2L. - A hardened steel ball (at least 810 Vickers hardness) may only be used on a material of hardness less than 450 and with a tungsten carbide ball on materials under HB 650.

Bottom it out, then back it off 4 (four) complete turns. Tighten nut and set screw. Mount the bracket and air cylinder using two bolts from existing motor/gearbox. (Figures 6, 8) Make certain the airline from the solenoid on the bracket is sticking out the bolt hole at the location where the air regulator installs.
